Defining the Thread Start Angle in SolidWorks

Defining the Thread Start Angle in SolidWorks

Defining the Thread Start Angle in SolidWorks

(OP)
Good Day,

I try to write out processes that I tend to forget in SolidWorks. Some of which I just seem to keep having to mess with the parameters to get it right. For some reason, I've had issues with how to orientate the drawing for forming threads so that they start at the top of a tube etc. it seems that based on starting points and planes picked (with a given starting angle). The results are usually the thread starts too low, or extends into the root cylinder's profile face.

I've posted on a site a way to do this, but I don't have a rule to follow about the starting plane (for the profile) as it relates to the starting angle (helix or curves).

RE: Defining the Thread Start Angle in SolidWorks

(OP)
two thoughts on that:

One is that it still does not addresses my real question of the start angles, side of part, and plane chosen (front and right). All of which may have more to do with the absolute orientation of solidwork's planes and where zero is (R or L).

the other is, dose it effect the way the features are dimensioned, or how the flights of the thread are tested for flexure etc.
